Alien genes

I dono if this has been posted
but i had a tought what if aliens had genes just like us and looked diffrent from each other.
i was thinking about that because there are so many discriptions photos that look alike but arent exactly alike.
also how they suposebly inpregnate a human with there child or w/e they do maybe the mothers genes give it a certain look : ) just an idea share your toughts

Interesting thought there you have. If we are both bi-pedal and even remotely shaped the same then it is quite possible that we share some of the same genetics. It makes sense that genetic material is a common part of the design of existing lifeforms.
